Energy Efficiency Elevation: The proportion of production capacity meeting benchmarking energy efficiency standards must increase by an average of 20 percentage points.

Capacity Optimisation: Production capacity falling below the baseline energy efficiency standards will be phased out entirely.

Emission Reduction Impact: Achieve cumulative energy savings equivalent to over 100 million tonnes of standard coal and cut $CO_2$ emissions by more than 200 million tonnes across key industrial sectors.

2. Key Mandates for the Cement Industry

The directive outlines explicit technological upgrades and retrofitting paths:

Process Optimisation: Prioritise energy-saving and carbon-reduction retrofits in critical processes like cement clinker production.

Advanced Equipment Adoption: Deploy high-efficiency technologies including 6-stage preheaters, 4th-generation clinker grate coolers with integrated center roller crushers, oxy-fuel combustion systems, and high-efficiency burners.

Grinding System Upgrades: Implement vertical roller mills (VRM) for finish grinding and separate grinding technologies.

Alternative Raw Materials & Fuels: Accelerate the transition toward green, low-carbon alternative materials and alternative fuels (AF).

Equipment Modernisation: Upgrade generic energy-consuming utilities including electric motors, fans, water pumps, heat pumps, air compressors, and transformers.

Phasing Out Obsolete Capacity: Fast-track the upgrade or decommissioning of inefficient assets, specifically targeting independent cement grinding stations with capacities under 600,000 tonnes/year.

Standardised Alternative Fuel Solutions by Harden

The implementation of alternative fuels (AF) is currently the primary lever for cement producers to substitute fossil fuels, mitigate carbon emissions, navigate stringent energy consumption caps, and balance environmental compliance with production costs.

Harden's alternative fuel preparation technology provides proven, commercial-scale, and highly efficient solutions tailored to meet these strict regulatory mandates and the technical requirements of cement kiln co-processing.

As a pioneer in drafting domestic alternative fuel industry standards, Harden leverages years of solid waste recycling and waste management experience.

We have engineered complete, custom RDF (Refuse-Derived Fuel), SRF (Solid Recovered Fuel), and ARF (Alternative Raw Material & Fuel) preparation systems specifically optimized for cement manufacturing.

Our systems process diverse combustible solid waste streams—including end-of-life tires (ELT), waste textiles, industrial pre-consumer waste, municipal solid waste (MSW), and excavated landfill waste.

Harden effectively addresses traditional industry pain points like mixed composition, irregular particle sizes, fluctuating calorific values, high moisture, and low combustion efficiency, perfectly matching the high-temperature, continuous, and stable combustion profiles required by cement kilns.

[Solid Waste Input] ➔ [Twin-Shaft Primary Shredder] ➔ [Smart Sorting/Screening] ➔ [Single-Shaft Fine Shredder] ➔ [High-Quality SRF/RDF (<50mm)]

Advanced Process Engineering: Harden's AF processing lines feature high-precision, multi-stage shredding integrated with intelligent closed-loop screening and multi-stage purification systems.

By combining twin-shaft primary shredding and single-shaft fine shredding with automated magnetic and air separation systems, our technology efficiently extracts metals, inert materials, and glass.

The system achieves an impurity removal rate exceeding 95% and guarantees a consistent output particle size below 50mm, ensuring high material uniformity and meeting the demands of continuous, large-scale cement plant operations.

Energy Efficiency & Kiln Compatibility: The high-quality alternative fuels produced feature a net calorific value (NCV) exceeding 4,000 kcal/kg and a stable moisture content below 15%. This ensures complete combustion, optimized suspension retention time, and high thermal efficiency within the kiln.

Remarkably, 1.8 tonnes of Harden's premium alternative fuel can replace 1 tonne of standard coal. This significantly increases the fossil fuel substitution rate (TSR), slashes coal consumption, and reduces net carbon and pollutant emissions during clinker production.

Sustainable Value & Circular Economy: Harden's alternative fuel preparation technology aligns with the green fuel substitution targets of the global cement sector. It enables cement manufacturers to rapidly deploy waste-to-energy and co-processing projects, diverting vast volumes of municipal and industrial solid waste from landfills.

This approach helps companies pass carbon audits, optimize energy structures, and phase out carbon-intensive processes. By integrating co-processing, cement producers can transition from traditional, energy-heavy operations to a low-carbon, circular economy model, driving sustainable, high-quality industry growth.

3. Regulatory Support & Policy Incentives

To guarantee these decarbonisation targets are met, the framework provides robust supporting mechanisms:

Financial Subsidies: Eligible energy-saving and carbon-reduction retrofitting projects can receive central investment subsidies covering up to 20% of the approved total investment.

Market-Driven Pricing: Regional authorities will streamline differential and tiered electricity pricing into a unified, market-driven mechanism to incentivize energy efficiency.

Carrots & Sticks: Carbon emissions avoided through successful technical retrofits can be credited as carbon offsets for future capacity expansions. Conversely, facilities that fail to modernize or remain non-compliant within the specified timeline will face mandatory closure.

This intensive energy-saving and carbon-reduction action plan sets a clear trajectory, actionable technical paths, and strong policy backing for the cement sector, accelerating its green transition toward mid-century net-zero goals.
